The below mentioned article provides a short note on the aminoacylation of tRNA. Role of Transfer RNA: Transfer RNA molecules play a key role in the process by delivering amino acids to the ribosome in an order specified by the mRNA sequence; this ensures that the amino acids are joined together in the correct order. Cells usually contain many species [...]
The following points highlight the three main stages for translation of RNA and protein synthesis. The stages are: 1. Initiation of Polypeptide 2. Elongation of Polypeptide: 3. Termination of Polypeptide. Translation of RNA: Stage # 1. Initiation of Polypeptide: Ribosomes exist as separate large and small subunits. The first step in translation involves the binding of the small ribosomal subunit [...]
The below mentioned article provides an overview on Ribonucleic Acid (RNA). In broad features, the chemistry of RNA is comparable to the chemistry of DNA. The chemical analysis shows the following two main differences in the polynucleotide chains of DNA and RNA: (i) The sugar in RNA is ribose whereas it is deoxyribose in DNA. (ii) While in DNA, the [...]
